概览

oaLayer 在 oapy 中可用，可通过 _tech 模块访问。

本页汇总 oaLayer 当前在 oapy 中可用的 Python 接口。

详细说明

The oaLayer class defines a layer that is later referenced to create a layer that is ultimately referenced when creating physical design data。 An oaShape or an oaFig can be placed on a layer。 Layers are used for multiple purposes and frequently correspond to the different manufacturing layers that exist on chips。 A shape refers to a layer using a layer number -- it is not bound to a layer object。 The oaLayer class can be observed by deriving from oaObserver 。

obj.destroy()

绑定状态: 已绑定

Python 调用: obj.destroy()

This function destroys this layer, removing it from the technology database。 This function unbinds any layer and lpp headers in open designs that are bound to this layer。 This function also destroys derived layers, viaDefs, viaSpecs that are dependent on this layer in the same oaTech ,。

Python 示例

from oapy._oa import _tech

# assume obj is a oaLayer
obj.destroy()

obj.getNumber()

绑定状态: 已绑定

Python 调用: obj.getNumber()

This function returns the number of the specified layer。

Python 示例

from oapy._oa import _tech

# assume obj is a oaLayer
obj.getNumber()

obj.getName(name)

绑定状态: 已绑定

Python 调用: obj.getName(name)

This function returns the name of the specified layer。

Python 示例

from oapy._oa import _tech

# assume obj is a oaLayer
obj.getName(name)

obj.getPeakACCurrentDensity()

绑定状态: 已绑定

Python 调用: obj.getPeakACCurrentDensity()

This function returns the peakACCurrentDensity value of this layer。 The returned value can be an oaFltValue , oaFlt1DTblValue , or oaFltIntFltTblValue 。 For a more detailed explanation of the usage of oaValues on this function, see Peak AC Current Density。

Python 示例

from oapy._oa import _tech

# assume obj is a oaLayer
obj.getPeakACCurrentDensity()

obj.getAvgACCurrentDensity()

绑定状态: 已绑定

Python 调用: obj.getAvgACCurrentDensity()

This function returns the avgACCurrentDensity value of this layer。 The returned value can be an oaFltValue , oaFlt1DTblValue , or oaFltIntFltTblValue 。 For a more detailed explanation of the usage of oaValues on this function, see Average AC Current Density。

Python 示例

from oapy._oa import _tech

# assume obj is a oaLayer
obj.getAvgACCurrentDensity()

obj.getRmsACCurrentDensity()

绑定状态: 已绑定

Python 调用: obj.getRmsACCurrentDensity()

This function returns the rmsACCurrentDensity value of this layer。 Valid value types are: oaFltValue , oaFlt1DTblValue , and oaFltIntFltTblValue 。 For a more detailed explanation of the usage of oaValues on this function, see RMS AC Current Density。

Python 示例

from oapy._oa import _tech

# assume obj is a oaLayer
obj.getRmsACCurrentDensity()

obj.getAvgDCCurrentDensity()

绑定状态: 已绑定

Python 调用: obj.getAvgDCCurrentDensity()

This function returns the avgDCCurrentDensity value of this layer。 The returned value can be an oaFltValue or oaFlt1DTblValue 。 For a more detailed explanation of the usage of oaValues on this function, see Average DC Current Density。

Python 示例

from oapy._oa import _tech

# assume obj is a oaLayer
obj.getAvgDCCurrentDensity()

obj.setNumber(number)

绑定状态: 已绑定

Python 调用: obj.setNumber(number)

This function sets the number of this layer to the specified value。 If the specified layer number exists, an oacLayerNumberExists exception is thrown。 Note: If this function modifies a layer number (a new number is set on a layer, which replaces a previous number set on this layer), this function unbinds the layer headers in all open designs that are bound to this layer。 If any layer headers exist in the opened designs with the new layer number, those headers are bound to this layer。 Similarly, this function will unbind any LPPHeaders that are bound to this layer in those designs, and will bind any LPPHeaders with the new layer number。 The function will destroy any derived sized layers, viaDefs, or viaSpecs in the same tech that depend on this layer。 The dependent objects are destroyed because they are bound to the layer by number (when the layer number changes, the binding is no longer valid)。

# assume obj is a oaLayer
